FILE JANDLING IN PYTHON

 CREATE  FILE IN D  DRIVE 

file = open("D:\\student.txt", "w")

file.write("Name: Rahul\n")

file.write("Course: Python Programming\n")

file.write("Marks: 85\n")

file.close()

print("File created successfully!")


OPEN  FILE  FROM D DRIVE 

with open("D:\\student.txt", "r") as file:
    data = file.read()

print("File Content:")
print(data)


FILE  EXIST  IN D DRIVE  HOW TO CHECK 

import os

file_path = "D:\\student1.txt"

if os.path.exists(file_path):
    print("File exists in D drive.")
else:
    print("File does not exist in D drive.")

FILE EXIST THEN CREATE NEW FILE 

import os

old_file = "D:\\student.txt"
new_file = "D:\\student_new.txt"

if os.path.isfile(old_file):
    print("Old file exists.")

    with open(new_file, "w") as file:
        file.write("This is a new file.\n")
        file.write("Created because student.txt already exists.")

    print("New file created successfully.")
else:
    print("Old file does not exist.")

Python none

  Python None Python None None is a special constant in Python that represents the absence of a value. Its data type is NoneType , and None is the only instance of a NoneType object. NoneType Variables can be assigned None to indicate "no value" or "not set". Example Get your own Python Server Assign and display a None value: x = None print (x) Use type() to see the type of a None value. Example Assign and print the data type of a None value: x = None print ( type (x)) Comparing to None To compare a value to None , use the identity operator is or is not Example Use the identity operator is for comparisons with None : result = None if result is None:    print ( "No result yet" ) else :    print ( "Result is ready" ) Example Similar example, but using is not instead: result = None if result is not None:    print ( "Result is ready" ) else :    print ( "No result yet" )

python random module

  Python Random Module example with resuly Python Random Module – Simple Examples with Results The Python random module is used to generate random numbers, select random items, and shuffle data. 1. Generate a Random Number import random   num = random . randint( 1 , 10 ) print ( "Random Number:" , num ) Result: Random Number: 7 The result can be different each time you run the program. 2. Generate a Random Decimal Number import random   num = random . random() print ( "Random Decimal:" , num ) Result: Random Decimal: 0.735421 3. Random Number Between Two Values import random   num = random . randrange( 10 , 50 , 5 ) print ( "Random Number:" , num ) Result: Random Number: 35 Possible results are 10, 15, 20, 25, 30, 35, 40, 45 . 4. Select a Random Item from a List import random   students = [ "Amit" , "Rahul" , "Priya" , "Neha...
